HEAT-EXCHANGE DEVICE.

Application filed March 26, 1926. Serial No. 97,752.

My invention relates to heat exchange devices and particularly to heating devices.

My invention has among its other objects the production of devices of the kind dea scribed which are compact, convenient, durable, eflicient and satisfactory for use wherever found applicable.

'A particular object of the invention is to provlde a heating device which may be re quickly and easily adjusted to project a column of heated air in a desired direction.

Une form of the invention is embodied in apparatus comprising a radiator core mounted upon a frame which is provided with passages communicating with the core. Also communicating with the passages are two nipples which are .co-axially disposed and are connected by unions to a steam header and a drain pipe. Mounted upon the frame is a motor for driving a fan adapted to provide a column of air through the co're. The frame, motor, fan and core may be angularly adjusted around the coincident axes of the nipples.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosures herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

lln the drawings, wherein like reference characters indicate like or corresponding parts:

Fig. 1 is a rear view of a device embodying the invention;

' Fig. 2 is a sectional view taken on line 22 of Fig. 1; and

Fig. 3 is a sectional view taken on line 33 of Fig. 1.

Referring to the drawings, wherein I have shown a preferred embodiment of the invention, the reference character designates in general a radiator core which is carried by a frame 11. The radiator core 10 may be of any'desired construction but preferably comprises tanks or headers 12 and 13 and a plurality of tubes 14; which extend between the headers,- the tubes 14 being preferably provided with cooling fins 15. The frame 11 preferably comprises integrally; formed U-shaped heads or manifolds 1? and 18, or the equivalent, which are provided with U-shaped passages 19 and 20, respectively, communicating with the headers 12 and 13, respectively. The heads 17 and 18 are preferably connected to each other by integral ribs 38 which carry an integral plate 39 adapted to support an electric motor 40, and secured to the shaft of the motor 40 is a fan 41 adapted to project a column of air through the radiator core 10. Any suitable means (not shown) may be' provided for connecting the motor 40 to any suitable source of electrical energy.

The means for securing the radiator core 10 to the frame 11 preferably comprises lugs 22 formed in the passages 19 and 20 and 7 tapped to receive bolts 23 (see Fig. 3), gaskets 25 being positioned between the radiator core 10 and the frame 11 if it is so desired. The bolts 23 preferably extend through the tanks or headers 12 and 13 and gaskets 25, or the equivalents for the purpose, are provided to prevent leaks between the heads of the bolts and the headers. U- shaped struts 23 are preferably provided in the tanks or headers 12 and 13 to prevent them from collapsing when the bolts 23 are screwed into the lugs 22.

Communicating with the passage 19 and screw-threaded to the head 17 is a nipple 27 which is co-axially disposed with respect to a nipple 28 screw-threaded into the head 18. The nipple 28 communicates with the passage 20. A union 30 connects the nipple 27 to a pipe 31 which may be connected in any suitable manner to a hot water pipe or to a so steam header or main 32. A. union 33 connects the nipple 28 with a pipe 35 which is connected in any suitable manner to a drain or return pipe 36.

The operationof the above described apparatusissubstantially as follows: Steam or hot water is admitted to the passage 19 by way of the nipple 27. The steam or water passes through the radiator core 10 to the nipple 28 and then flows into the return or 11;: weasel drain pipe. Obviously, there will be an exchange of heat between the radiator core and the air and if steam is employed, it will be condensed as it passes through the radiator core. The im roved a paratus may be angularly adjusted around the coincident axes of-the nipples 27 and 28 to direct the heated column of air to any desired point, it being understood that the unions 30'and 33 readily permit such angular adjustment.

Having thus described my inventlon, it is obvious that various. immaterial modifica tions may be made in the same withoutv departin from the spirit of my invention; hence it-do not wish to be understood as limiting myself to the' exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
